You can make your own labels on your sewing machine. Draw a square or rectangle the size you want the label on a piece of fabric. If you have a machine with a small alphabet on it, you can use that for your message (don't cut the square/rectangle out until you have completed your message, it will be easier to work with a larger piece of fabric vs. a small label) or use a permanent fabric marker to write in your message. I usually put steam-a-seam on the label afterwards to stabilize it and then cut out the label. Fuse it to your quilt and use a zig zag or satin stitch or a decorative stitch if your machine has them to go around the edge of the label to hide the raw edges.
